The Index Mapping Cypher is defined by passing the integer string to get the specific string. In Python, we have some built−in functions such as str(), len(), join(), and, int() will be used to solve the problem based on Index Mapping Cypher. Let’s take an example to understand this: The given string, my_str = “Hyderabad” The given index, idx = 101456 The final result becomes yHyrab Syntax The following syntax is used in the examples- str() This is a built−in function in Python that accepts any value to convert it into string. len() This is a built−in method ...

In Python, we have some built−in functions like str(), replace(), split(), strip(), and, len() that will be used to solve Interconvert Horizontal and vertical String. Python allows us to convert strings between horizontal and vertical instructions with simple steps by improving readability, formatting, text manipulation, visual creativity, and programming applications. Syntax The following syntax is used in the examples- str() This is an in−built function in Python that converts the value to a string. It prints the value as a string. replace("", "") The replace is a built−in method in Python that accepts two parameters− and "" ... Read More

Python has a variety of built-in methods to modify and analyze the text, that contains to find the specific element within them. To solve this problem statement it will use some built-in functions like next(), filter(), and, lambda to find the first even element from the list. The various applications are- data filtering tools, and, content filtering tools. Let’s see how to take the input of the program to get the result: The given list, List_1 = [21, 33, 12, 11, 61, 78] The final result becomes 12 because it is the first even number from the list. Syntax The ... Read More

The dictionary is one of the four data types in Python that doesn’t allow any key duplicates. In this problem statement, we have to create two dictionaries as user input and check the matches for a common key. If key elements are found as common then it prints the result. This can be possible by using various methods in Python such as type(), items(), set(), etc. Let’s take an example of this: Input: A = { ‘I’: 10, ‘II’: 20, ‘III’: 30, ‘IV’:40 } B = { ‘II’: 40, ‘V’: 60, ‘VI’: 80, ‘I’: 90 } Output: { ‘I’, ‘II’ ...

In Python, a tuple is one of the four built−in data types that is used to collect the data and this data is represented by round parenthesis i.e.(). Tuple is generally known for multiple collections of items into a single item. In Python, we have some built−in functions like map(), tuple(), and, lambda will be used to Convert Matrix to Custom Tuple Matrix. The custom tuple matrix is defined by a subclass of a tuple that has elements and it is separated by a comma to create the sublist(list represents matrix). Let’s take an example of this: Original Matrix: ... Read More

In Python, Tkinter is GUI(Graphical User Interface) based library that accesses easier and faster ways to build the GUI application. The Tkinter Label Widget will be used to build the border that helps to improve the visibility of the user interface. A Tkinter Label Widget is such type of area that shows the text or images. In Python, we have some built−in functions such as Label(), TK(), Frame(), pack(), and, config() will be used to Set the Border of Tkinter Label Widget. Syntax The following syntax is used in the examples- Tk() The Tk() is a built−in function in ... Read More

The multiple subplots are defined by assigning different graph plots. Plotly is a powerful Python library for creating interactive visualizations for data research and presentation. Its capacity to put up multiple subplots, that are independent plots placed within a single figure, is one of its primary characteristics. This feature allows us to compare and display various datasets or variables side by side, giving us a simple overview of the data. In Python, we have some built−in functions− add_trace, update_layout, and, show which can be used to set up multiple subplots with group legends using Plotly in Python. Syntax The ... Read More

The smallest missing number is the smallest number that is missing from a stream of elements or in an Array. The stream may or may not contain continuous elements. If the stream is continuous then the smallest missing number is nothing but the Smallest Missing Number in a stream. In this section, we will discuss the various approaches to find a Smallest Missing Number in a stream of elements using Java programming language. Problem Statement Given a stream of integers find the smallest missing number from the stream. Input 1 arr=[1, 2, 3, 5, 6, 7, 8] Output 1 ... Read More

Lost Number is the number which is missing from a continuous stream of elements or in an Array. In this section, we will discuss the various approaches to find a lost number in a stream of elements using java programming language. Example for a lost number in an array Lost number is a number which is missing from a continuous sequence of a numbers in an array. Example 1 Consider an array: arr=[1, 2, 3, 4, 5, 6, 8] In the above array ‘arr’, 7 is missing, so 7 is the lost number Example 2 Consider an array: arr=[1, ... Read More

A TreeMap is a class provided by Java that implements Map Interface. It is a collection of key-value pairs and the key-value pairs in TreeMap are stored in sorted order based on key values. An Entry is defined as a key-value pair in a TreeMap. In this article, we will look in detail how to get TreeMap key-value pair or entry greater or less than the specified value. Methods Used Now, we will be looking into some of the inbuilt methods and their functionality of TreeMap which are used in this particular article. higherKey() − This method is ... Read More
